knock? - Honda Prelude Forum

black98lude · 03-04-2002, 04:59 PM

I hear a slight knock(once) everytime I start to move forward from a complete stop. sometimes knocking sound comes from the bottom front(mostly) and sometimes the same knock at the bottom rear. (seems like it was there b4 and dissappeared for a while and it's back again)
It kinda feels like the car is strechting as though it is yawning

does anyone know what's up!!
thnx

Do you use 91 + Octane??

mine does it too.. but only when it's cold. Not sure what it is but doesn't seem to be harming anything.

yes I do use 91+octane, mostly 92!
but it does not seem like it's coming from the engine...cuz I do sometimes here it from the backside(sounds more like chasis twisting!)
